	# In order to be updated when nightlies fail, please subscribe for updates on PR:
	# ---> https://github.com/facebook/metro/pull/1314 <---
	# where comments will be published on fail.

	# This is a bit of a workaround tackling the lack of an organic way
	# to notify certain people when a Github workflow fails:
